Dear Bug Team!
In Tcl mode, if I try to fill a set of comment lines, XEmacs enters an
infinite loop, eating all the CPU it can. It's easy to cause: create
a file with a .exp extension, and xemacs goes into Tcl mode. Type a
few lines with leading '#' characters, put the cursor in the lines
somewhere, and hit M-q, which is bound to fill-paragraph-or-region.
In other languages, this fills the paragraph, taking care of the
comment delimeter on every line. In Tcl mode it causes XEmacs to
infinite loop.
You should be able to C-g out of the infinite loop
This sounds like the filladapt-mode bug that was in an older version
of prog-modes (1.53). If you look at the definition of tcl-mode in
prog-modes/lisp/tcl.el you should see code that looks like this:
;; XEmacs change: check for filladapt-mode.
(if (not (and (boundp 'filladapt-mode)
filladapt-mode))
(progn
(make-local-variable 'fill-paragraph-function)
(setq fill-paragraph-function 'tcl-do-fill-paragraph)))
and not this:
(setq fill-paragraph-function 'tcl-do-fill-paragraph)
When I kill the runaway processfrom another process, I get this
dump:
Lisp backtrace follows:
...
tcl-do-fill-paragraph(nil)
You have a bunch of lisp shadows load path shadows here,
I'm wondering if you are accidentally getting an old version of tcl.el.
